nmeioneefi concern: Be.. 1t;kncwn: that; I, ALFRED LARSON, cit-izen ofjtheUni-ted States, residing at Scobey,

:in theconnty of valley and State of Montana; have invented certain new and useful Improvements in Spring-Wheels, of which the followingis:hi pecificationi Yllle presentinvention relates to certain new andluseful.lginiprovements in the con- -struct i on of wheels of that type which derive the required resiliency from metallic springs which are, so -arranged ast'o absorb all shocks and jarsand prevent the same from reaching the axle or body of the vehicle.

The object of the invention is toprovidca wheel embodying a peculiar construction and arrangementof the spring'menibers which permits of the resiliency-being regulated to accommodate the wheel tolight or-heavy loadsf For iulldescription of the invention and the merits. thereof and also to acquire a knowledgeoflthe. details of construction and the means for effecting-the result,- reference to be had to the following description and accompanying drawings, inwhich:

:2. A spring wheel in which the spokes are cooperating with each other to impart resiliency to the wheel, keys arranged between-the variousgpairs. of extensions, and

cams for moving the keys to regulate the ten-- sion in the spring extensions.
